driving me absolutely crazy for the past week and a half.
replaced the dexcool in my car and got an air pocket in my coolant system. tried bleeding using the screw on the tstat housing, as well i have replaced my thermostat.i've tried lifting the front end off the ground to help the air out, bubbling through the rad cap, spent 4 hours yesterday running the car and getting it to burp air out of the bleeder screw but again this morning i get no heat unless the rpm's are above 4000. cracked the bleed screw this morning and it just pisses coolant with no air. rad hose right before t-stat is warm as well.
what i'm getting at is there any specific procedure to bleed these systems? searched through mitchell/all data and no specific procedure for coolant replacement.
i'm also suspecting maybe i got a bad t-stat?
any advice would be good
